  To: git

This patch series adds new command line options to git-commit to make
it easy to specify messages for commits correctly formatted for use
with 'rebase -i --autosquash'.

This iteration (v7) addresses criticisms about implementation details
raised against the v6 series.  For details, see

http://thread.gmane.org/gmane.comp.version-control.git/159547

The first patch introduces minor refactorings that set the stage
for subsequent patches, mostly preventing copy-n-paste coding in what
follows.

The second patch teaches format_commit_message to reencode the content
if the caller's commit object uses an encoding different from the
commit encoding.

The remaining patches add the --fixup and --squash commands to
git-commit including tests of commit, interactions with rebase and
i18n encodings.  

One issue which limits the testing (but not the implementation, I
think) is that when 'rebase --autosquash' is comparing commit subject
lines it does not first make sure that the commits use a common
encoding.  That's follow-on work.

* builtin/commit.c: Replace block of code with a one-liner call to
  logmsg_reencode().

* commit.c: new function for looking up a comit by name

* pretty.c: helper methods for getting output encodings

  Add helpers get_log_output_encoding() and
  get_commit_output_encoding() that eliminate some messy and duplicate
  if-blocks.

format_commit_message() will now reencode the content if the desired
output encoding is different from the encoding in the passed in
commit.  Callers wanting to specify the output encoding do so via the
pretty_print_context struct.

This option makes it convenient to construct commit messages for use
with 'rebase --autosquash'.  The resulting commit message will be
"fixup! ..." where "..." is the subject line of the specified commit
message.

Example usage:
  $ git commit --fixup HEAD~2

From: Pat Notz @ 2010-11-02 19:59 UTC (permalink / raw)
  To: git

This option makes it convenient to construct commit messages for use
with 'rebase --autosquash'.  The resulting commit message will be
"squash! ..." where "..." is the subject line of the specified commit
message.  This option can be used with other commit message options
such as -m, -c, -C and -F.

If an editor is invoked (as with -c or -eF or no message options) the
commit message is seeded with the correctly formatted subject line.

Example usage:
  $ git commit --squash HEAD~2
  $ git commit --squash HEAD~2 -m "clever comment"
  $ git commit --squash HEAD~2 -F msgfile
  $ git commit --squash HEAD~2 -C deadbeef

Sorry if I've missed earlier versions and this has already been
answered. You can carry forward Cc's if you like and thus earlier
commentators will be more likely to re-review your code.

This doesn't mention the editor being invoked. The editor is invoked
only with certain option combinations right? I'm expecting this:

uses editor
------------
--squash
--squash -c
--squash -t
--squash -eF
--squash -eC
--squash -em
--squash --amend

doesn't use editor
------------------
--squash -C = no editor
--squash -m = no editor
--squash -F = no editor

I haven't thoroughly checked the code to make sure that's happening.
